Dear all, When relaxing over a mince pie or ice cream sundae (for those of
you in warmer climes) try one of the four card games on fraction matching
this month on the NRICH website, one at each of levels one
http://www.nrich.maths.org/public/viewer.php?obj_id=2729&part=index&refpage=monthindex.php,
two
(http://www.nrich.maths.org/public/viewer.php?obj_id=2730&part=index&refpage=monthindex.php),
three
(http://www.nrich.maths.org/public/viewer.php?obj_id=2738&part=index&refpage=monthindex.php)
and four
(http://www.nrich.maths.org/public/viewer.php?obj_id=2739&part=index&refpage=monthindex.php).
There are also a number of Tough Nuts still to be cracked and these can be
found at http://www.nrich.maths.org/public/toughnuts.php.
The picture puzzler is based on the tiled floor at Lafayette in Paris:

How many different shapes can you see inside this photograph? What fraction
of the image is grey?
All the problems on fractions and ratio are still accessible of course and
why not answer the NRICH questionnaire at
http://freeonlinesurveys.com/rendersurvey.asp?id=73617 if you haven't done
so already?
We hope all those of you taking time off during this month have a relaxing
break and every one here at NRICH sends you season’s greetings.
